Plant performance measurement often stops at the point where power enters the plant switchyard. Yet minor transformer failures can have devastating impact on plant performance and system reliability.

Watch this video to explore how a transformer is used to increase and decrease potential difference. This equation can be used to calculate what the output might be from a particular transformer, or ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...
